"My Heart Will Go On" is the theme song of the 1997 blockbuster film Titanic. With music by James Horner, lyrics by Will Jennings, and production by Walter Afanasieff, it was recorded by Céline Dion. It became one of the best-selling singles of all time, and was the world's best selling single of 1998.
The song was recorded in one take and without instrumental accompaniment. Horner, Dion, and later Sony Music Entertainment decided to use this first recording because "Dion's voice was perfect."
Horner had originally composed the song as an instrumental motif that is used in several scenes during Titanic. He then wanted to make a full vocal song out of it, for use in the end credits of the film. Director James Cameron did not want such a song, but Horner went ahead anyway and got Jennings to write the lyrics. Dion was Horner's first choice to sing it, but when she heard the song, she did not want to record it. It was her manager and husband, Rene Angelil, who convinced her to record a demo version, which was something she hadn't done for many years.
Horner waited until Cameron was in an appropriate mood before presenting him with the song. After playing it several times, Cameron declared his approval, although worried that he might be criticised for "going commercial at the end of the movie."
